[http://free-electrons.com Free Electrons] has performed flash filesystem benchmarks, with funding from the [http://www.celinuxforum.org/ CE Linux Forum]. This page is the starting point to present how those tests are performed and what results were obtained.

Free Electrons created Python scripts that automate the execution of commands through a serial line (including bootloader and kernel booting), and measure the time taken to execute these commands. The scripts were designed to be generic, and support for new boards can easily be added by creating board specific Python definitions. The complete details of what tests are performed and how measurements are made are available in the [[Flash Filesystem Benchmarks Protocol]] page.

=== Test automation scripts ===

The current version of these scripts can be found on [https://gitorious.org/ffs-benchmarks/ffs-benchmarks gitorious], and are released under the terms of the GPLv2 license. Working board automation files are provided for the [[http://www.calao-systems.com/articles.php?lng=en&pg=5932|CALAO USB-A9263-C02]] and [[http://www.igep.es/index.php?option=com_content&view=article&id=46&Itemid=55|IGEPv2 boards]]. You will need to build a root filesystem to run the tests on and create filesystems of different sizes (8, 32, 252 and 508 MB) to be tested ; both of which that have been used by Free Electrons will be available soon.

Test methodology

Free Electrons created Python scripts that automate the execution of commands through a serial line (including bootloader and kernel booting), and measure the time taken to execute these commands. The scripts were designed to be generic, and support for new boards can easily be added by creating board specific Python definitions. The complete details of what tests are performed and how measurements are made are available in the Flash Filesystem Benchmarks Protocol page.

The current version of these scripts can be found on gitorious, and are released under the terms of the GPLv2 license. Working board automation files are provided for the [USB-A9263-C02] and [boards].
